I am trying to connect two Cisco ASR 920 routers at both end of Nortel 8600 switches. The two Cisco ASR have IP address configured X.X.X.1/30 and X.X.X.2/30 in both end. I did not able to make this working. There is a WAN/Trunk link between the two Nortel 8600 already. Here are the things I did and it will be good to know if you can provide me some advice how to fix this. I know it is pretty simple thing and I could not make this working though....

Just want to add here that there are multiple VLAN groups and I believe that I need to add the VLAN in right group so that the access ports and WAN ports are in the same group and ports are forwarding.

This is a point to point VLAN and I am trying to extend two router connection over this Nortel 8600 network.Any advice will be great.

Cisco#1 - Access port to 8600#1 - Also access port. New VLAN ID.MLT has new VLAN tagged to it on 8600#1.MLT has new VLAN tagged to it on 8600#2.8600 #2 has access port created with new VLAN assigned.Access port on Cisco#2 connects to new 8600#2 access port.

It will be good to know what will be the trouble shooting steps and commands in Nortel 8600. There are multiple VLAN groups and I believe I need to create VLANs and add to the right group. So that all ports are in forwarding state.

Any link to a good documentation/troubleshooting guide will help a lot.
